1.Character:
It is quiaxed crystal system, cube, octahedron or dodecahedron. Colorless crystal or white powder. Extremely insoluble in water. Soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, insoluble in acetone. It dissolves in aluminum salt and iron salt solution to form complex, and reacts with hot concentrated sulfuric acid to produce hydrofluoric acid. Hydrogen fluoride can be prepared by reacting calcium fluoride with concentrated sulfuric acid in a lead container. Can form eutectic with various metal oxides.
The uses of calcium fluoride mainly include the following aspects:
1.Aluminum smelting: Calcium fluoride as an additive to bauxite, can control the melting point and increase the yield of aluminum.
2.Metallurgical industry: Calcium fluoride can be used as a flux and slag in the steel and casting industry, which can effectively reduce the oxidation rate and melting point of metals.
3.Ceramics, glass and glazes: Calcium fluoride can be used as raw materials for ceramics and glass to increase their hardness and transparency, and in products such as glazes and reflective finish paints.
4.Chemical industry: Calcium fluoride is used in the production of chemicals such as fluoride and fluorocarbons.
5.Semiconductors, electronics, optics and pharmaceuticals: Calcium fluoride can also be used for material preparation in these fields.
6.Other fields: Calcium fluoride is also used in the manufacture of special lenses, fluorspar abrasives, and as a raw material for certain optical products.
7.Light, optical, engraving and defense industries: Calcium fluoride is also used in these industries.
8.Water treatment: Adding calcium fluoride to drinking water can help prevent dental disease, usually in concentrations of 1-1.5ppm.
